The present invention relates to partial self-winding mechanisms, which after the original winding of series of springs, tend to rewind the prime-actuating springs, and

cause the whole mechanism to run quite long period, without rewinding.

In the drawings, 1 have illustrated a complete embodiment of the invention, and in which,

Figure 7 is an end viewof Figure 6, taken from the right thereof.

Figure 8 is a plan view of a clutch and associated parts, taken online 88' of Figure 7.

Figure 9 is a front elevation of a sawtable and saw, belted to the front central shaft of the present invention.

Figure 10 is a partial side elevation of Fig ure 9, taken from the right side thereof.

In the drawings, the numerals 1, 2, 3, indicate supports, which are rigidly mounted in the base plate 4, by means of the socket cast- 3 ings 5, 6, 7 as shown.

Mounted in the supports 1, 2, 3 preferably in roller bearings, are a series of shafts 8, 9,

10 etc. which carry the planetary gears 11, 12, 13 etc. on one end thereof respectively,

and on their opposite ends said shafts carry the rewinding gears 14, 15, 16 etc. As seen in Figure 1, the gears. 11, 12, 13 engage the periphery of the rim-gear 17, and the internal teeth 18 of the latter engage the idler gears 19, 20, 21. The idler gears are each mounted on their respective shafts 22, 23,

24, carried by the support 1, and preferably by roller bearings therein,

The idler gears 19, 20, 21 engage the teeth 50 of the front central gear 25, mounted on the central shaft 26, which shaft extends through the machine, having bearings in the supports 1, 2 and 3. It will be seen that the rim-gear 17 is supported in alignment by the three roller guides 27, 28 and 29, the details of which are shown in Figure 3 of the drawings, in which a base cas ing 30, is surmounted by the cap-casting 31 and both securely attached to the support 1, by means of the bolts 32, 32. The castings 30 and 31 are preferably split-castings, so that the rollers 33, 34 can be conveniently mounted in them as shown in Figure 3. The rollers 33, 34 engage the faces of the rim-gear 17, and it is evident that as the rim-gear is revolved by the planetay gears 11, 12, etc. the rollers will keep the rim-gear in vertical alignment with the actuating gears just named, and with the idler gears 19, 20 and 21.

It is evident that when the actuating gears 11, 12, 13 operate the rim-gear, and the central gear 25, (as will be explained hereinafter), that a brake may be necessary to control the speed of the machine. This is provided by the device shown in Figures 4 and 5' in which a 7 suitably padded lever 35, hinged at 36 to the casting 37 which last is mounted at 38 on the supporting wall 1. The amount of pressure exerted on the rim-gear 17 by the lever is governed by means of the locking bar 39, hingedly mounted on the support 1, as shown at 40, Figures 4 and 5. It will be seen that the locking-bar 39 is provided with a series of indentations 41, 41 which engage over the lever 35, whereby governing the intensity of pressure exerted against the face of the rimgear 17.

Referring to the Figure 2 of the drawings, it will be seen that on each of the shafts 8, 9, 10 are mounted coil-springs 42, 43, 44 respectively, the inner ends of which are each rigidly attached to the shafts, while the out-. er ends of said springs, are each attached to the pins 45, 45 etc. mounted in the support 2. It will also be seenthat the shafts 8, 9, 10 etc. are each made up of two disconnected portions, to wit, 46, 47; and that between 7 these sections or parts there is inserted a clutch, 49. The teeth of clutch 49 are preferably formed so that a clock-wise actuation mitting of portion 47 of shaft 8 for instance, will be transmitted through clutch 49 to the portion 46 of shaft 8, and thereby actuate gear 11. It will also be evident, that when the spring 42 is wound up, same will supply such actuation of shaft 8. The clutch 49 is spring-held as shown by the spring 51, and the two halves 52, and 53 of said clutch. From which description it is clear that when the spring 42 actuates portion 47 of shaft 8, that the portion 53 will actuate portion 52 of said clutch and thus turn portion 46 of the shaft. It is equally clear, that if portion 47 of shaft 8 is actuated in an anti-clockwise direction, as observed from the left in Figure 6, that the teeth 54, would merely ride on each other, and no motion would be transmitted to portion 46, nor gear 11. The purpose of this arrangement of parts will be more fully explained-as the description proceeds.

it is seen from Figures 1, 6 and 7 of the drawings that when the front central gear is actuated by means of the gears shown in Figure 1, and before explained, that such actuation will be transmitted through the shaft 26 to the rear central gear 55 mounted in the support 3. This gear is provided with teeth 56 on its peripheral face 57, and is adapted to transmit motion received through shaft 26,

i by means of said teeth to the rewinding gears 14, 15, 16 etc. These rewinding gears are loosely and revolubly mounted on section 47 of the shafts 8, 9, 10 etc. audit is evident that as portion 47 of the shaft last named revolves in a clockwise direction as seen from the left of Figure 6, by means of the actuation of the springs 42, 43, 44 etc. the gears 14, 15, 16 etc. will receive no motion from said shafts. 1

However as the rear central gear revolves in a clockwise direction, it is clear that the said gears 14, 15, 16 etc. being in mesh therewith will normally revolve in an anti-clockwise direction, but are incapable of transsaid motion to unless acted on by the clutches 58, 58, as will now be explained. Each shaft 8, 9, '10, etc. is provided with a clutch 58, 58, etc. the right side of which 59 is slidable on the portion 47 of said shafts in a longitudinal direction as seen in Figure 6 of thedrawings. The portion 60 on which the portion 59 rides is of an angular cross-section as shown in Figure 8, so that when the teeth of part 59 are operated in an anti-clockwise direction as observed from the left of Figure 6, the portion 60 of the shafts 8, 9, 10 will also be turned in an anticlockwise direction, and ascan be seen from an inspection of the teeth of clutch 49, when such a motion takes place in the portion 47 of the gear shafts, the teeth of clutch 49 merely click past each other, and do not interfere with the motion of the gears 11, 12, 13 etc. and heretofore mentioned in this specificat-ion.

the shafts 8. 9, 10 etc.

It is seen in Figures 6 and 7 of the drawings that the part 59 of clutch 58, carries a grooved casting 61 rigidly mounted thereon which slides longitudinally with part 59 on the shaft end 60. In Figures 6, 7 and 8 there is shown an annular partor ring 62, which is mounted by means of the extensions 63, 63 etc. on the rear central gear 55, and revolves constantly with it. This ring 62 is in continuous engagement with the grooves 64 of the castings 61 as shown. The ring 62 has on its outer side a depressed portion 65, extending approximately from 66 to point 67 Figure 7 and on its inner face the ring 62 is provided with a bossed or raised portion 68 of substan tially equal length to the depressed portion just described. 7

From Figure 8 it is evident that as the ring 62 is revolved the part 59 of clutch 58 will be actuated along the shaft in a longitudinal direction, according to the position of the portion 69 of the ring, and the location of the bossed portion 68, in that when portion 68 engages the groove of the part 61, the portion 59 of the clutch will then be moved into engagement with the teeth of the part 70 of said clutch 58. W' hen this action takes place it is evident that the anti-clockwise motion being constantly received by the gears 14, 15, 16 from the gear 57, will then be transmitted through means of the clutch 58 to the end 60 ofthe shafts 8, 9, 10 etc., and said shafts will then revolve in 'an anti-cloclc wise direction, and wind up the springs 42, 43, 44 etc. a

From the Figure 7 it is seen that as gear 55 revolves the bossed portion 68 of the ring 62 will reach the various rewinding clutches 58 on the shafts 8, 9, 10 etc. successively, and practically one at a time, so that as all the main springs 42, 43, 44, etcaare tending to operate the rear central gear 55 as before eX- plained, it is evident that'as the latter revolves it can then wind up partially each successive spring, 42, ing with the steady operation of the main central shaft of the machine 26, since each portion 47 is actuated in turn, the clutch 49 on the particular shaft being rewound frees the planetary gears 11, 12 etc. from the turning motion it otherwise would receive in an anti-clockwise direction. -In order to give the springs 42, 43 etc. their initial winding to start the machine, it is necessary to either apply a crank 71 on the angular end of the part 60 of each planetary gear shaft individually, or when the mechanism is not too large and powerful, the whole rear central gear may be revolved by manual power using the handle located at72 Figure 7, and in this way more quickly wind up the various actu ating springs 42, 43, 44 etc.

From what has been said, it is believed the operation of device is readily understood, but will be briefly outlined. The springs 42, 43,

43, etc., without interfer- 44 etc. are first completely wound up as just described. The actuating springs then tend to transmit motion through the clutches 49 on all of the planetary gear shafts 8, 9, etc. to the planetary gears 11, 12, 13, etc. These in turn set in motion the rim gear 17, the idlers 19, 20, 21, and they in their turn set the front central gear in motion. T o prevent the mechanism moving at too great a speed, the brake shown and described in Figures 1, i and 5 is used, against the side face of the rim-gear as heretofore explained. The front central gear 25, actuates the cen tral shaft 26, and turns the rear central gear constantly. The latter is constantly in mesh with the rewinding gears 14, 15, 16 etc., and when the bossed portion of the ring 62 engages the groove of the part 61 of the clutch 58, on any particular planetary gear shaft, such as 8, for instance, the clutch is thrown into operation, the portion 47 of the shaft 8 is operated in an anti-clockwise direction, and the particular spring such as &2 in this instance is partially rewound, by the successive revolutions of the rear central gear 57. This procedure just described, of course appliEs to all the springs e3, le etc, and before the springs are completely run down, it is evident that they have all been partially rewound many times, thereby extending the running operation of the original winding received to quite a lon period.

It is apparent that the main central shaft 26 can be extended either at the front or rear of the machine, and the power obtained from the springs 42, 43, 44 etc. can be used in any suitable way for setting toys in operation, or where powerful springs are used power may be obtained for many purposes from the central shaft 26.

By way of illustration of one of the many uses of this mechanism, 1 have shown in Figures 9 and 10 of the drawings, the central shaft 26 belted to a circular-saw. The shaft 26 is somewhat extended as stated above to permit the belt 73 to be mounted on it. A circular-saw 74 is revolubly mounted on the shaft 77, the latter being mounted in the sawtable 75 as shown. On the shaft 7'? is also mounted the revoluble pulley 76, which is belted to the shaft 26 of the self-winding mechanism. It is evident that as the shaft 26 revolves the saw Tel will be operated to saw lumber placed on the table 75. The saw and table may be either of toy size, or they may be made of large size, sufficient for mill use, according to the size and strength of the driving mechanism which forms the subject of this invention.
